MEANS FOR LOCKING AUTOMOBILE STARTING-CBANKS.

Specification of Letters Patent.

Application filed October 14, 1910. Serial No. 587,007.

To all whom it may concern.-

Be it known that I. WILLIAM J. N. DAVIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful lmprt'iver nent in Means for Looking Automobile Startirig-Cranks, of which the following is a specification.

The object of my invention is to prov 1de simple and effective means for preventing the theft; of automobiles by locking their starting-cranks.

My invention is designed for use with the starting crank which is inseparably secured .in place on an automobile and is mutually springdield ottt of engagement wtth the shaft, requiring the crai'ik-steni to be forced inwardly to engage it therewith preparatory to cranking.

in the acconmanying drawings Figure I is a broken view in elevation. partly sectional. showing a starting-crank in place on an autot'noltile and provided with my improvement in one form of embodiment; Fig. '3 i an enlarged view in elevation of my de- \lti shown in Fig. t: Fig. I is a view shovw ing the -tarting-erank as in Fig. l but provid d ith a modilied form of my locking t t-vir' and Fig. -l is an enlargedy section on hu t. lig.

hie form of my lot-king device. shown in titan. l and 2; comprises a collar 5 formed of vo rtt 'tlb hinged together to lit about the llti'lttQlif-lil'tlll'll lillif part of the stem 6 n5 n ;:t!t'1h1tlitlt tarting-crank T. and it is gum-plot} on ll. l'rt-e t lgts with perforated t';tt'- h through .t'lll 'll in pa the lttls'p of :t padlock f r lurking the collar in its operative position about that part of the crank. win-re in; t-onl inennrnt between the t'ranlcartn I and -t';t1i'$.--tem receiving socket in the automo ile causes it to act as a stop against moving the stem inwardly against the resistance of the outwardlytlu'owing =pring ll to clutch .it with the starting-shalt f the aut mobile.

.\nother form of embodiment of my invention. shown in Figs. 3 and 4. consists of a pin l2. pretm'ably ot' the flat and wide l'm-m shown. havin'e a [head 13 and insertil'ile through longitudit'ntl slot 14 provided in the protruding part of the eranlcstem ('t.

vent the inward movement of the start-ingcrank for the cranking purpose.

lVhat I claim as new and desire to secure by Letters Patent is- 1. A locking device of the class described, comprising a sleeve designed to be removably fitted to a cranking-shaft and to extend between the crank thereon and the support through which the shaft is mounted and constituting an abutment for preventing longitudinal movement of the shaft.

2. A locking device of the class described, comprising an abutment consisting of hinged sections, the device being adapted for application to a cranking shaft .with the sections thereof embracing the shaft and extending between the crank thereon and the support through which the shaft is mounted. and means for holding the sections of the sleeve assembled about the shaft.

3. In a locking device of the class described, a two-part sleeve adapted to be removably fitted upon a cranking-shaft and to extend between the crank of the shaft and the support through which the shaft is mounted and to serve as an abutment for holding the shaft against longitudinal movement. and means holding the parts of the sleeve assembled.

4. A device of the class described, comprising a sleeve consisting of hinged sections provided with apertnred ears at their free edges, the sleeve being adapted for disposal about a cranking-shaft and to extend between the crank thereon and the support through which the shaft is mounted and to constitute means for preventing longitudinal movement of the shaft, and a lock having a hasp engaged through the apertures in the said ears. A 5. In combination with the starting-crank of an automobile, having its stem normally held yieldingly outof engagement with the starting-shaft. a stop on the normally-protruding portion of the crank-stem between the cranlchandle and stem-receiving socket, to obstruct inward movement of the stem, the stop being readily removable bodily from the crank-stem. and a lock for temporarily securing the stop against removal, for the purpose set. forth.

I. In combination with the starting-crank v of an automobile, having its stem normally I held yieldingly out of engagement with the l starting-shaft, a collar about the normally ne the p n al o atl'ords a stop to pre- 1 protruding portion of the t-ranlcstem bestarting-shaft, a collar compi'ising hinged sections fitting about the normally-protruding portion of the crank-stem between the tween the crank-handle and stem-receiving l socket to obstruct inward movement of the stem, saidcollar being formed of separable section's adapting it to be readily applied to I crank-handle and stem-receiving socket, 5 and removed from the crank-stein,- and a l perforated ears on the free ends of the collock for temporarily securing the collar-secl la'r, and a lock engaging said ears, for the tions together about the stem, for the p111"- l purpose set forth. pose'set forth.
